14 players stayed on Halo 2 just to play it while the other million or so players went on to Halo 3 and Reach and Halo 4 and stuff.
No please.
If you like Halo 2 so much, go back and play it. Time and time again we've seen that you can, even now that they've shut down Halo 2 servers. Any true dedicated fans would probably do so.
Yes, Halo 2 was a good game. No, Halo 2 will never be the Best Halo ever made because that is a subjective opinion and not an objective fact and can never ever be so.
Yes, Halo 2 was addicting. No, it most probably wasn't because there were abusable glitches in it. Did it make gameplay 'skillful'? Yes, you could argue that, but being able to press B, then X, then B isn't exactly something I see as 'skillful' compared to map control, good aiming, tactical play and using your brain.
Bring back elements? Yes. I, for one, believe that the ranking systems of Halo 2/3 that required skill to get a higher rank was a godlike system that was the very pure reason as to why the game lasted so long. An MLG playlist made that even better. But not button combos.
TL;DR - Halo 2 was a great game. No doubt about it. But it certainly couldn't have been the BEST ever halo game, otherwise it would still be sold, people will still be playing it tons, etc. I want elements of Halo 2 in new games because those elements made Halo 2 something that would be great - but I don't want Halo 2 back. I want something new, not something old.
(Button Combos don't make a game, yeah?)
